Soft soldering fluxes - Test methods - Part 16: Flux efficacy test, wetting balance method (ISO 9455-16:2013)
ISO 9455-16:2013 specifies a method for the assessment of the efficacy of a soft soldering flux, known as the wetting balance method. It gives a qualitative assessment of the comparative efficacy of two fluxes (for example, a standard and a test flux), based on their capacity to promote wetting of a metal surface by liquid solder. The method is applicable to all flux types in liquid form classified in ISO 9454‑1.
Flussmittel zum Weichlöten - Prüfverfahren - Teil 16: Bestimmung der Wirksamkeit des Flussmittels, Verfahren zur Messung der Benetzungskraft (ISO 9455-16:2013)
Dieser Teil der ISO 9455 legt ein Verfahren zum Beurteilen der Wirksamkeit eines Flussmittels zum
Weichlöten fest, das als Verfahren zur Messung der Benetzungskraft bezeichnet wird. Es bietet eine
qualitative Beurteilung für den Vergleich der Wirksamkeit zweier Flussmittel (z. B. ein Standard-Flussmittel mit
einem zu prüfenden Flussmittel) hinsichtlich ihrer Fähigkeiten, die Benetzung einer Metalloberfläche durch ein
flüssiges Weichlot zu fördern. Das Verfahren ist für alle flüssigen Flussmitteltypen anwendbar, die in
ISO 9454-1 aufgeführt sind.
ANMERKUNG Es ist anzunehmen, dass zukünftige Entwicklungen, welche mit verbesserten Verfahren einen
reproduzierbaren Oberflächenbereich zum Prüfen ergeben, es möglich machen, dieses Verfahren zum Beurteilen der
Flussmittelwirksamkeit quantitativ einzusetzen. Aus diesem Grund sind verschiedene alternative Verfahren zur
Vorbereitung der Prüfstückoberfläche in der vorliegenden Norm enthalten.
Flux de brasage tendre - Méthodes d'essai - Partie 16: Essai d'efficacité du flux, méthode à la balance de mouillage (ISO 9455-16:2013)
L'ISO 9455-16:2013 spécifie une méthode pour l'évaluation de l'efficacité d'un flux de brasage tendre, connue sous le nom de méthode à la balance de mouillage. Elle permet une évaluation qualitative de l'efficacité comparée de deux flux faisant l'objet d'une comparaison (par exemple un flux de référence et un flux d'essai), évaluation fondée sur la capacité de ces flux à faciliter le mouillage de la surface d'un métal par le produit d'apport liquide. Cette méthode est applicable à tous les types de flux sous forme liquide classés dans l'ISO 9454-1.
Talila za mehko spajkanje - Preskusne metode - 16. del: Preskus učinkovitosti, postopek za merjenje omočljivosti (ISO 9455-16:2013)
Ta del ISO 9455 določa metodo za oceno učinkovitosti talila za mehko spajkanje, znano kot postopek za merjenje omočljivosti. Na osnovi zmogljivosti spodbujanja omočljivosti kovinske površine s tekočim talilom podaja kvalitativno oceno primerjalne učinkovitosti dveh talil (npr. standardnega in preskusnega talila). Ta metoda velja za vse vrste talil v tekoči obliki iz ISO 9454-1.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9455-16 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 12, Soldering materials.
This second edition cancels and replaces the first edition (ISO 9455-16:1998), which has been

INTERNATIONAL STANDARD ISO 9455-16:2013(E)
Soft soldering fluxes — Test methods —
Part 16:
Flux efficacy test, wetting balance method
1 Scope
This part of ISO 9455 specifies a method for the assessment of the efficacy of a soft soldering flux, known
as the wetting balance method. It gives a qualitative assessment of the comparative efficacy of two
fluxes (for example, a standard and a test flux), based on their capacity to promote wetting of a metal
surface by liquid solder. The method is applicable to all flux types in liquid form classified in ISO 9454-1.
NOTE It is hoped that future developments using improved techniques for obtaining a reproducible range
of test surfaces will enable this method for assessing flux efficacy to be quantitative. For this reason, several
alternative procedures for preparing the surface of the test piece are included in the present method.
